Landlord and Tenant are parties to that certain lease dated August 21, 2008 ("Lease"). Pursuant to the Lease, Landlord has leased to Tenant space currently containing approximately 4,542 rentable square feet (the "Original Premises") described as Suite No. 980 on the 9th floor of the building commonly known as Tabor Center 1 located at 1200 17th Street, Denver, CO 80202 (the "Building").

Tenant has requested that additional space containing approximately 2,050 rentable square feet described as Suite No. 975 on the 9th floor of the Building shown on Exhibit A hereto (the "Expansion Space") be added to the Original Premises and that the Lease be appropriately amended and Landlord is willing to do the same on the following terms and conditions.

Expansion and Effective Date.

Effective as of the Expansion Effective Date (defined below), the Premises, as defined in the Lease, is increased from 4,542 rentable square feet on the 9th floor to 6,592 rentable square feet on the 9th floor by the addition of the Expansion Space, and from and after the Expansion Effective Date, the Original Premises and the Expansion Space, collectively, shall be deemed the Premises, as defined in the Lease. The Term for the Expansion Space shall commence on the Expansion Effective Date and end on the Termination Date. The Expansion Space is subject to all the terms and conditions of the Lease except as expressly modified herein and except that Tenant shall not be entitled to receive any allowances, abatements or other financial concessions granted with respect to the Original Premises unless such concessions' are expressly provided for herein with respect to the Expansion Space, except that the Remaining Allowance for the Original Premises shall be available as provided in Section 8.02 below.

The Expansion Effective Date shall be the later to occur of (I) April 1, 2010 ("Target Expansion Effective Date"), and (ii) the date upon which the Landlord Work (as defined in the Work Letter attached as Exhibit B hereto) in the Expansion Space has been Substantially Completed (as defined below); provided, however, that if Landlord shall be delayed in Substantially Completing the Landlord Work in the Expansion Space as a result of the occurrence of a Tenant Delay (defined below), then, for purposes of determining the Expansion Effective Date, the date of Substantial Completion shall be deemed to be the day that said Landlord Work would have been Substantially Completed absent any such Tenant Delay(s). The Landlord Work shall be deemed to be " Substantially Complete" or "Substantially Completed" on the date that all Landlord Work has been performed, other than any details of construction, mechanical adjustment or any other similar matter, the non-completion of which does not materially interfere with Tenant's use of the Premises as reasonably agreed to by Tenant. If the parties cannot agree on whether Substantial Completion has been achieved, Landlord's architect shall make the final determination. A"Tenant Delay" means any act or omission of Tenant or its agents, employees, vendors or contractors that actually delays substantial completion of the Landlord Work, including, without limitation, the following:

Tenant's failure to furnish information or approvals within any time period specified in the Lease or this Amendment, including the failure to prepare or approve preliminary or final plans by any applicable due date (in which event the Tenant Delay shall be deemed to be the shorter of (i) the actual time by which the Tenant's failure exceeds the specified time period or (ii) the delay in completion of the Landlord Work resulting from the Tenant Delay);

Tenant's selection of equipment or materials that have long lead times after first being informed by Landlord that the selection may result in a delay (in which event the Tenant Delay shall be deemed to be the shorter of (i) the actual time by which the Tenant's failure exceeds the specified time period or (ii) the delay in completion of the Landlord Work resulting from the Tenant Delay); and Landlord shall place orders for any long lead time items within ten (10) days of accepting the final bid for Landlord Work,

Changes requested or made by Tenant to previously approved plans and specifications;

The performance of work in the Expansion Space by Tenant or Tenant's contractor(s) during the performance of the Landlord Work; or

If the performance of any portion of the Landlord Work depends on the prior or simultaneous performance of work by Tenant, a delay by Tenant or Tenant's contractor(s) in the completion of such work,

The adjustment of the Expansion Effective Date under Section 1.02 above and, accordingly, the postponement of Tenant's obligation to pay Rent on the Expansion Space shall be Tenant's sole remedy and shall constitute full settlement of all claims that Tenant might otherwise have against Landlord by reason of the Landlord Work not being Substantially Complete on the Target Expansion Effective Date.

In addition to the postponement, if any, of the Expansion Effective Date as a result of the applicability of Paragraph 1.02, of this Amendment, the Expansion Effective Date shall be delayed to the extent that Landlord fails to deliver possession of the Expansion Space for any other reason (other than Tenant Delays by Tenant), including but not limited to, holding over by prior occupants, Any such delay in the Expansion Effective Date shall not subject Landlord to any liability for any loss or damage resulting therefrom, If the Expansion Effective Date is delayed, the Termination Date under the Lease shall not be similarly extended.

Base Rent. In addition to Tenant's obligation to pay Base Rent for the Original Premises, Tenant shall pay Landlord Base Rent for the Expansion Space as follows:

All such Base Rent shall be payable by Tenant in accordance with the terms of the Lease. Landlord and Tenant acknowledge that the foregoing schedule is based on the assumption that the Expansion Effective Date is the Target Expansion Effective Date. If the Expansion Effective Date is other than the Target Expansion Effective Date, the schedule set forth above with respect to the payment of any installment(s) of Base Rent for the Expansion Space shall be appropriately adjusted on a per diem basis to reflect the actual Expansion Effective Date, and the actual Expansion Effective Date shall be set forth in a confirmation letter to be prepared by Landlord. The effective date of any increases or decreases in the Base Rent rate shall be postponed in accordance with any adjustment of the Expansion Effective Date as provided above.

Additional Security Deposit. No additional security deposit shall be required in connection with this Amendment.

Tenant's Pro Rata Share. For the period commencing with the Expansion Effective Date and ending on the Termination Date, Tenant's Pro Rata Share for the Expansion Space is .3585%. For the avoidance of doubt, for all periods prior to the Expansion Effective Date, the Tenant's Pro Rata Share of Expenses and Taxes for the Original Premises shall remain as described in the Lease.

Expenses and Taxes. For the period commencing with the Expansion Effective Date and ending on the Termination Date, Tenant shall pay for Tenants Pro Rata Share of Expenses and Taxes applicable to the Expansion Space in accordance with the terms of the Lease.

Improvements to Expansion Space.

Condition of Expansion Space. Tenant has inspected the Expansion Space and agrees to accept the same "as is" without any agreements, representations, understandings or obligations on the part of Landlord to perform any alterations, repairs or improvements, except as is expressly provided otherwise in this Amendment, including any and all Landlord Work as set forth in Section 6.02 below and Exhibit B.

Responsibility for Improvements to Expansion Space. Landlord shall perform Improvements to the Expansion Space in accordance with the Work Letter attached hereto as Exhibit B.

Early Access to Expansion Space. During any period that Tenant shall be permitted to enter the Expansion Space prior to the Expansion Effective Date (e.g., to perform alterations or improvements, if any),Tenant shall comply with all terms and provisions of the Lease, except those provisions requiring payment of Base Rent or Additional Rent as to the Expansion Space.

Remaining Allowance. The parties acknowledge that there is approximately $28,603.00 remaining from the Allowance granted in the Lease for the Original Premises ("Remaining Allowance"). Landlord agrees to allow the Remaining Allowance to be used for the installation of improvements in the Premises and/or the Expansion Space pursuant to the terms of the Work Letter attached to this Amendment as Exhibit B as if the Remaining Allowance was the Expansion Allowance (as defined below).
